Abstract:This paper proposes the use of backward simulation with Modelica as a tool to improve system design. The aim is to introduce system simulation into early design stages of mechatronic systems and to use the same software tools and model libraries that are also used in later stages for dynamic analysis and control design. It seems that the necessity of a control design is one of the main obstacles against the use of conventional dynamic system simulation in early design stages.

The main benefit of backward simulation is that it does not require an implementation of feedback control. The backward simulation approach is explained using the example of a servo-hydraulic drive. The paper shows that it can help to significantly reduce the energy consumption of this system. It is possible to simulate typical duty cycles of the drive without the need to redesign the control for each change.
